Finding out you have gestational diabetes is already a lot. Then add nausea—whether it's pregnancy nausea, gestational diabetes nausea, or both—and suddenly eating feels impossible. You're supposed to control blood sugar levels, but you can barely keep food down. You're not failing. This is genuinely hard, and you're not alone.
Here's the thing: managing gestational diabetes while dealing with extreme nausea isn't just about willpower or finding the "right" food. It's about understanding what your body needs right now, and giving yourself permission to do things differently than the textbook says.
When you're diagnosed with gestational diabetes, you're already managing elevated blood sugar levels and insulin resistance. Add nausea to that mix, and suddenly eating the balanced meals your diabetes educator or registered dietitian recommended feels impossible. The goal shifts from "perfect" to "sustainable."
Let's talk about what's actually happening, and more importantly, what can actually help.
Honestly? It might be both, and it doesn't really matter which one is "causing" it—you still feel sick either way.
Pregnancy nausea is real and peaks in the first and early second trimester (usually weeks 6–16), driven by rising hormones. It often improves by the second half of pregnancy, though some expecting mothers deal with it the whole way through.
Gestational diabetes nausea is different—it's less common than pregnancy nausea, but it can happen, especially if blood glucose levels are running high or unstable. Some pregnant women also feel nauseous from low blood sugar (hypoglycemia), though that's usually paired with shakiness, sweating, or dizziness. Extreme nausea paired with blurred vision or extreme fatigue warrants a call to your provider.
The real kicker? If you're dealing with both, they can feed into each other. Nausea makes it hard to eat balanced meals. Skipping meals or eating imbalanced meals makes blood sugar harder to manage. And unmanaged gestational diabetes with unstable blood sugar can make nausea worse.
Julija note: If you're in early pregnancy and just diagnosed with gestational diabetes, nausea is probably pregnancy-related. But if nausea is new or worsening in the second trimester or later, or if it's paired with other symptoms (blurred vision, extreme fatigue, feeling unwell), mention it to your provider—it could be gestational diabetes-related or something else worth checking.
When you feel sick, your body is stressed. Stress hormones (cortisol, adrenaline) can actually raise blood sugar levels, even if you're not eating. So you might have high blood sugar and nausea, which feels unfair because you're not even eating much.
Plus, nausea makes it hard to eat the balanced meals that actually keep blood glucose levels stable. You might skip meals, eat only carbs (because they're easier to tolerate), or eat at weird times. All of that makes managing gestational diabetes feel impossible.
The goal here isn't perfection. It's eating something that:
Keeps you from getting too hungry (which makes nausea worse)
Doesn't spike your blood sugar levels
Actually sounds tolerable
Once you're diagnosed with gestational diabetes, your healthcare team (likely including a registered dietitian or diabetes educator) will create a treatment plan focused on controlling blood sugar levels through diet, exercise, and possibly medication. Most women can manage gestational diabetes effectively with lifestyle changes, though some need insulin injections or other medications. If you’re newly diagnosed and everything feels like too much right now, this gestational diabetes toolkit gathers all the necessary resources to get you started.
Prenatal care becomes more frequent—you'll have more frequent checkups to monitor both your blood glucose levels and your baby's health. The goal is to deliver healthy babies and prevent serious complications for both you and your baby.
But here's what they don't always tell you: managing this while dealing with extreme nausea is a whole different ball game.
Certain factors increase your risk of developing gestational diabetes:
Family history of diabetes or family history of gestational diabetes
Previous pregnancy with gestational diabetes
Weight gain or being overweight before pregnancy
Ethnicity (higher risk for American Indian, Hispanic, Asian, and Pacific Islander women)
Age (first pregnancy after age 25)
High blood pressure before pregnancy
Insulin resistance or PCOS
If you have any of these risk factors and you're dealing with extreme nausea, managing your blood sugar becomes even more critical—and even more challenging.
Most pregnant women get a glucose tolerance test (usually a glucose test between weeks 24–28). If your blood sample shows elevated blood sugar levels, you might need a follow-up test. Once diagnosed with gestational diabetes, you'll work with your healthcare team on a special diet and exercise management plan.
But again—if you're nauseous, following that plan feels nearly impossible.
If you've ever been told to "just eat something" when you're nauseous, you know how unhelpful that is. But for pregnant women managing gestational diabetes, it's even more complicated because not all "somethings" are equal.
A regular pregnant person with nausea might grab crackers, ginger ale, or toast. Those are fine for them. But for you, plain crackers or sugary ginger ale can spike your blood glucose levels and leave you feeling worse 30 minutes later when the spike crashes.
So you're stuck: you feel sick, you're hungry, but you also can't just eat whatever sounds tolerable. That's a lot of pressure, and it's completely valid to feel frustrated about it.
Here's what I want you to know: your blood sugar doesn't take a break just because you feel sick. Your body is still managing glucose, your placenta is still releasing hormones, and your insulin resistance is still there.
But—and this is important—you also don't have to eat a "perfect" gestational diabetes meal when you're actively nauseous. The goal is harm reduction: eat something that keeps your blood sugar stable enough, even if it's not textbook.
Unmanaged gestational diabetes increases health risks for both you and your baby, including:
Serious complications during pregnancy and delivery
Birth defects or developmental issues
Baby weighing too much (macrosomia), which can complicate delivery
Possible complications after birth (low blood sugar in baby, breathing issues)
Greater risk of type 2 diabetes later for both you and your child
But here's the thing: you can't manage what you can't eat. So the real goal is finding ways to eat something balanced, even if it's not perfect.
Protein is your friend here because it:
Keeps you fuller longer (so you're not hungry + nauseous)
Stabilizes blood glucose levels (no spike-and-crash)
Often feels less "heavy" than carb-heavy foods
Easy protein options when nauseous:
Cheese cubes or string cheese (cold, salty, satisfying)
Hard-boiled eggs (batch cook them; eat cold or at room temp)
Greek yogurt (creamy, protein-packed; some mamas find cold yogurt easier to tolerate)
Nuts or nut butter (small handful of almonds, or a spoonful of almond butter)
Cottage cheese (cold, protein-rich, less "heavy" than it sounds)
Protein shake or smoothie (if solid food feels impossible; use unsweetened almond milk, protein powder, Greek yogurt, cottage cheese, nut butter, etc.)
The trick: eat these before you're starving. Waiting until you're ravenous + nauseous makes everything worse.
Nausea often comes with a weird food aversion—sweet things sound gross, hot foods feel overwhelming, and you crave salt or sour flavors instead.
Work with that, not against it:
Salty snacks: olives, pickles, salted nuts, cheese
Cold foods: cold chicken, cold shrimp, cold pasta salad with olive oil + veggies
Sour flavors: lemon water, lime juice on food, pickled veggies, sauerkraut
Umami (savory): miso broth, soy sauce, nutritional yeast sprinkled on things
These often feel more tolerable than sweet or heavy foods, and they're blood sugar-friendly.
When managing gestational diabetes, you still need carbs—both you and your baby do. The key is choosing whole grains and pairing them with protein:
Whole grain toast with cheese or nut butter
Brown rice or whole grain pasta (smaller portions, paired with protein)
Overnight oats with protein shake as a base (add nut butter, nuts, seeds)
Whole grain crackers with cheese
Avoid the "no carb" trap—it doesn't help with nausea, and it deprives you and your baby of needed nutrients.
Nausea + pregnancy = dehydration risk. And dehydration can actually worsen nausea and make blood sugar harder to manage.
But plain water can feel blah or even make nausea worse for some mamas.
Try:
Electrolyte drinks (coconut water, or a pinch of salt + lemon in water)
Read more in our full electrolytes guide during pregnancy.
Bone broth (salty, warm or cold, feels more substantial than water)
Herbal tea (ginger, peppermint, or chamomile; cold or warm depending on what sounds good and is approved by your provider)
Sparkling water with lemon (sometimes the bubbles feel refreshing)
Aim for small, frequent sips rather than chugging a big glass.
Instead of three big meals, try eating smaller amounts more often:
Every 2–3 hours, eat a small snack that has protein + a tolerable carb
This keeps you from getting too hungry (which makes nausea worse) and keeps blood glucose levels more stable
Example mini-meals:
Cheese + a few whole grain crackers
Hard-boiled egg + a slice of whole grain toast
Greek yogurt + a small handful of berries
Turkey slices (reheat) + an apple
Handful of nuts
If you're supposed to eat three meals a day but that feels impossible, adjust. Eat when you can, in amounts you can tolerate. Your provider would rather see you eating small, balanced snacks than forcing big meals and feeling worse.
If you're testing blood sugar, you might notice that smaller, more frequent meals actually give you steadier blood glucose levels anyway.
Regular exercise helps control blood sugar levels, but when you're nauseous, moderate exercise is all you need:
A gentle 10–15 minute walk after meals can help stabilize blood glucose
Prenatal yoga or stretching (if it doesn't make nausea worse)
Swimming (if you have access and feel up to it)
Don't push yourself. Even light movement helps.
Some mamas find relief with:
Ginger (ginger tea, ginger candies, ginger supplements—check with your provider on dosage)
Peppermint (tea, or just smelling peppermint oil)
Vitamin B6 (some research suggests it helps with pregnancy nausea; ask your provider about dosage)
Acupressure bands (worn on the wrist; some mamas swear by them)
None of these are magic, but they might take the edge off, which makes eating a bit easier.
Mention nausea to your care team if:
It's severe or getting worse (not improving by mid-second trimester)
You're losing weight or unable to keep food down
You're feeling dizzy, faint, or extreme fatigue
You're worried about your blood sugar because you can't eat enough
You have blurred vision or other concerning symptoms
Your provider might suggest medication (like vitamin B6 or prescription anti-nausea meds), and that's okay. Managing nausea is part of managing your health during pregnancy and treating gestational diabetes effectively.
If you have access to a registered dietitian or diabetes educator, they can help you modify your treatment plan for nausea. They understand that managing gestational diabetes while dealing with extreme nausea requires flexibility. Be honest about what you can and can't eat.
I get it—you're managing blood sugar, so maybe you think cutting carbs entirely will help. But:
You need carbs for energy and for your baby
No-carb eating often leads to nutrient gaps
It can actually make nausea worse because you're not eating balanced meals
It's not sustainable, especially when you already feel awful
Instead of no carb, aim for balanced carbs: whole grains, fruit, legumes—paired with protein and fat.
I know eating when nauseous feels counterintuitive. But skipping meals:
Makes nausea worse (low blood sugar + hunger = more nausea)
Makes blood sugar management harder (your body gets stressed, hormones spike)
Leaves you more vulnerable to overeating later
Increases health risks for unmanaged gestational diabetes
Eat small amounts, frequently, even if it's just a bite.
If something sounds gross, don't eat it. Your body is telling you something. There are plenty of other protein and carb options.
Managing gestational diabetes is hard. Pregnancy nausea is hard. Together, they're a lot. And if you're also dealing with work, other kids, partner stress, or anything else, it's even more.
You're not failing if you're eating smaller meals, or if some days your blood sugar numbers aren't perfect, or if you're relying on foods that aren't "ideal" but are actually tolerable.
Your body is growing a human, managing hormonal changes, dealing with insulin resistance, and fighting nausea. That's a lot. Be gentle with yourself.
Did you eat a balanced snack today even though you felt sick? That's a win. Did you drink water? Win. Did you test your blood sugar even though you were exhausted? Win. Did you ask for help or talk to your provider? Huge win.
Progress isn't linear, and it doesn't have to be perfect. It just has to be yours.
You're doing the work to keep yourself and your baby safe, even when it feels impossible. That matters. Managing nausea while controlling blood sugar isn't easy, but you're not alone—and you're not failing.

1. Can gestational diabetes cause nausea?
Yes, though it's less common than pregnancy nausea. High or unstable blood glucose levels can cause nausea, especially in the second trimester or later. If nausea is new or worsening, mention it to your provider.
2. What's the best thing to eat when nauseous with gestational diabetes?
Something with protein + a tolerable carb, eaten in small amounts. Cheese + crackers, hard-boiled eggs + toast, or a protein shake often work well. Cold, salty foods are often easier to tolerate than hot or sweet foods.
3. Will skipping meals help my nausea?
No—skipping meals usually makes nausea worse and makes blood sugar management harder. Eat small, frequent amounts instead.
4. Is it okay to eat smaller meals if I'm nauseous?
Absolutely. Smaller, more frequent meals often help with both nausea and blood glucose stability. Your provider would rather see you eating tolerable amounts than forcing big meals.
5. Should I take medication for nausea while managing gestational diabetes?
Talk to your provider. Some options (like vitamin B6 or certain anti-nausea meds) are safe during pregnancy and gestational diabetes. Your provider can help you find what works.
